From: Aditya Pakki <pakki001@xxxxxxx> [ Upstream commit 89dfd0083751d00d5d7ead36f6d8b045bf89c5e1 ] In tipc_nl_compat_sk_dump(), if nla_parse_nested() fails, it could return an error. To be consistent with other invocations of the function call, on error, the fix passes the return value upstream. Signed-off-by: Aditya Pakki <pakki001@xxxxxxx> Signed-off-by: David S.
